To all whom it may concern: 7

Be it known that I, JOHN E. KILBURN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain *new and useful Improvements in Car-Seats, (Case A,) of which the following is a specification.

This invention relates to car-seats and more particularly to seats of the non-reversible type in which the back is stationarily mounted at the rear edge of the seatcushion.

The primary object of the invention is to provide an improved form of support for the cushions of a car-seat of this type which is of light weight and at the same time possesses the requisite degree of strength.

Further objects of the invention are to provide a seat-support which may be manufactured at low cost, which is of attractive appearance and which permits of using cushions, and particularly a seat-cushion, which are of the maximum length.

One feature of the invention involves the provision of a seat-support which is a combined seat-end and back-supporting arm, these two parts being formed from a single piece of sheet-metal. Such a single piece seat-end and arm may be formed integral with a suitable base-portion or a separate pedestal may be provided on which the combined seat-end and arm are mounted.

The invention further involves the provision of a supporting structure for the cushions of a car-seat consisting of a horizontally-disposed member for supporting the seat-cushion, an arm for supporting the back-cushion and an off-set between these two parts whereby the back-supporting arm is displaced from the plane of the seat-end in the direction of the length of the seat. In this way it is possible to have the backsupporting armsecured to the end of the baclecushion and at the same time to have the end of the seat-cushion extend beyond the end of the back-cushion whereby the seat-cushion is made of the maximum length to give the greatest amount of seating surface and the back-cushion is made of slightly less length so that the aisle adjacent to the'end of the seat will be of greater width above the seat-cushions where such greater width is desired. In a standard of this character for supporting the seat-and back-cushions of a car-seat, the, standard is subjected to the greatest strain at the angle therein where the horizontal and upright members of the standard join and it is essential that it be of small size at this point so as not to encroach upon the space directly in rear of the seat. For this reason a standard constructed in accordance with the in vention is provided with a reinforce at the angle therein which reinforce extends over the offset in the standard and overlaps the adjacent ends of the back-supporting arm and the member which supports the seatcushion. This reinforce is united to the standard preferably by. welding .so that along the offset in the standard,.the latter is of box-section and hence of great strength.

The reinforced offset between, the supports for the seatand back-cushions above referred tomay be, and preferably is, employed in the form of a seat-support wherein the seat-end and the back-supporti11g arm drawings in which Figure 1 is a front view of a car-seat broken away and sectioned inpart, Fig. 2

is an end view of the seat, Fig. 3 is a view l of the inner side of the combined seat-end and back-supporting arm, Fig. 1 is a sectional view on line 1-1 of Fig. 7 Figs. 5 and 6 are sectional Views on lines 5-5'and 6-6, respectively, of Fig. 3, Fig. 7 is a rear view of the standard shown in Fig.3, Fig. 8 is a section on line 8 8 of Fig, 3, Fig. 9 is a front view of a modified form of seat, Fig. 10 is a view of the standard employed in the seat shown in Fig. 9' and Fig. 11 is a section on line 1111 of Fig. 10.-

Referring'first to vFigs. 1 to 8 inclusive, the seat illustrated consists of a back-cushion 12-and a seat-cushion 13 supported on V 8 inclusive. This supporting structure is formed from a single piece of sheet-metal shaped to provide a horizontally-disposed portion which constitutes the seat-end and an upwardly extending back-supporting arm 16. The piece of sheet-metal, after being cut to the proper configuration is pressed to the desired form, preferably, that indicated in the drawing. The shaping of the sheet-metal piece includes the provision of an offset 17 therein so that the arm 16 is displaced from the plane of the seat-end 15 in the direction of the length of the seat. The cross-sectional shape of the back-supporting arm 16 is preferably that shown in Fig. 5 from which it will be seen that an integral flange 18 is provided upon the arm 16 which flange is adapted to bear against the rear face of the back-cushion when the arm proper is secured to the ends of the back-cushion.

The horizontally-disposed portion 15 of the seat-support which constitutes the seatend, is provided with an inwardly-turned flange 19 along the upper and lower edges thereof and along the front edge. The combined seat-end and back-supporting arm thus constructed is strengthened at the angle therein where it is subjected to the greatest strain. This is done by providing a re inforce at the angle which reinforce extends over the offset 17 and the adjacent ends of the seat-end and back-arm. This reinforce is shown at "20. A piece of sheet-metal is bent in the direction of its length as required by the offset 17, preferably in the manner shown in Fig. 8. Vhen the piece 20 is thus shaped it is secured to the flanges at the edges of the combined seat-end and backarm preferably by welding so that the structure is made of box-section throughout the offset therein and the parts adjacent to the offset. As shown in Fig. 3 the reinforce is extended up within the back-supporting arm 16 a short distance so as to insure that it will be firmly secured to the backsupporting arm.

The seat-end portion of the seat-support I; is preferably stiffened by the .application to the inner side thereof of a sheet-metal plate.

Thisplate is shown at 21. Over most of its surface it is spaced apart from the body-portion of the seat-end 15 but its edges 22 are shaped down so as to lie against the inner side of the seat-end 15. These edges 22 are welded to the seat-end.

The combined seat-end and back-supportingarm thus constructed is secured to the ends of connecting. rails 23. Forthis purpose end-pieces 24 are riveted to the ends of the connecting rails 23 and bolts 25 passed through these end pieces and openings provided therefor in the seatend. hen the nuts on the inner ends of these bolts 25 are tightened up. the combined seat-end and shown in Fig. 3, but the forward end piece is of greater height than the rear one and.

is provided with a pin 26 upon its upper face. The seat-cushion 13 is mounted upon these end pieces 24:, it being held in position by the pin 26 which enters an opening in its frame. The size of the end-pieces 24 is such that the cushion will be maintained at the proper inclination. The back-cushion 12 has its end secured to the back-supporting arm 16 with the rear face of the cushion bearing against the flange 18.

By this construction it will be seen that the seat is provided with a seat-end, that this seat-end and the back-supporting arm are formed integral and that by reason of the offset in this integral seat-support the seatcushion may be made longer than the backcushion. This is desirable as it is important to make the seat-cushion of the maximum length in order to givelarge seating surface and the seat-cushion may be made longer than the back-cushion as the aisle at the end of the seat may be narrower on a level with the seat-cushion than it is above those cushions. By forming the offset back-supporting arm and seat-end from a single piece of sheet-metal and reinforcing the structure over the offset and the angle at the joint between the arm and seat-end, the requisite amount of strength is provided and yet the structure may be made of such small dimensions that it will not obstruct free entrance to the space immediately in rear of the seat.

In Figs. 9, 10 and 11, a somewhat similar construction is employed differing from that shown in the preceding'figures in the respect that the horizo-ntally-disposed portion of the seat-support is not a seat-end; instead, this horizontally-disposed portion extends under the seat-cushion and supports the latter upon its upper face. Referring to these figures, the standard consists of a horizontally disposed portion 26 and a back-supporting arm 27 formed from a single piece of sheet-metal, there being an offset 28 between them so that the arm 27 is displaced if desired; in any case the reinforce 29 will extend along the offset and around the angle in the standard. I The horizontally-disposed member of the standard has flanges 30 at its upper, lower and front edges and a pin '31 is mounted upon the upper flange 30.

' Gussets 32 are preferably provided for pressing the flanges 30.

The standard shown in Fig. 10 is mounted upon a pedestal 33 of any suitable construction and a seat-cushion is supported upon the flange 30 at the upper edge of the horizontally-disposed arm 26 of the standard with the pin 31 entering an opening in the seat-cushion. The back-cushion has its end secured to the back-supporting arm 27 With the rear face of the cushion bearing against the flange formed on the rear edge of arm 27.

In the constructions above described, the body of the standard is formed from a single piece of sheet-metal, this piece forming both the horizontally-disposed portion and the upwardly-extending arm of the standard. But in some cases, as When the offset 18 very small, tWo sheet-metal pieces may be employed, these being Welded together so that they are in effect a single piece. I Wish it understood, therefore, that this latter construction is included Within the scope of the appended claims.

-Having described my invention, What I claim as new therein and desire to secure by Letters Patent of the United States is:

1. In a car-seat, a support formed of sheet-metal and comprising a horizontally disposed flanged, cushion supporting member, an upwardly extending flanged, backsupporting arm offset from said member so as to lie in a plane displaced in the direction of the length of the seat from the plane of said member and an offset portion connecting the arm and member and integral with both of them, a sheet-metal reinforce for said combined arm and member extending throughout said offset portion, and secured to the flanges of said member and arm so that the complete offset portion is of box-section, a back-cushion having its end secured to said arm, and a seat-cushion of greater length than the baclrcushion mounted upon said member, substantially as set forth.
